KDE 2.0 Development, Which Is Directly Supported

The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development.
KDE Free Qt Foundation Strengthens Qt

How the KDE Free Qt Foundation strengthens Qt by Olaf Schmidt-Wischhöfer (board member of the foundation)1, December 2019 Executive summary The development framework Qt is available both as Open Source and under paid license terms. Two decades ago, when Qt 2.0 was first released as Open Source, this was excep- tional. Today, most popular developing frameworks are Free/Open Source Software2. Without the dual licensing approach, Qt would not exist today as a popular high-quality framework. There is another aspect of Qt licensing which is still very exceptional today, and which is not as well-known as it ought to be. The Open Source availability of Qt is legally protected through the by-laws and contracts of a foundation. 1 I thank Eike Hein, board member of KDE e.V., for contributing. 2 I use the terms “Open Source” and “Free Software” interchangeably here. Both have a long history, and the exact differences between them do not matter for the purposes of this text. How the KDE Free Qt Foundation strengthens Qt 2 / 19 The KDE Free Qt Foundation was created in 1998 and guarantees the continued availabil- ity of Qt as Free/Open Source Software3. When it was set up, Qt was developed by Troll- tech, its original company. The foundation supported Qt through the transitions first to Nokia and then to Digia and to The Qt Company. In case The Qt Company would ever attempt to close down Open Source Qt, the founda- tion is entitled to publish Qt under the BSD license. This notable legal guarantee strengthens Qt.
Building a Distribution: Openharmony and Openmandriva

Two different approaches to building a distribution: OpenHarmony and OpenMandriva Bernhard "bero" Rosenkränzer <[email protected]> FOSDEM 2021 -- February 6, 2021 1 MY CONTACT: [email protected], [email protected] Way more important than that, he also feeds LINKEDIN: dogs. https://www.linkedin.com/in/berolinux/ Bernhard "bero" Rosenkränzer I don't usually do "About Me", but since it may be relevant to the topic: Principal Technologist at Open Source Technology Center since November 2020 President of the OpenMandriva Association, Contributor since 2012 - also a contributor to Mandrake back in 1998/1999 2 What is OpenHarmony? ● More than an operating system: Can use multiple different kernels (Linux, Zephyr, ...) ● Key goal: autonomous, cooperative devices -- multiple devices form a distributed virtual bus and can share resources ● Initial target devices: Avenger 96 (32-bit ARMv7 Cortex-A7+-M4), Nitrogen 96 (Cortex-M4) ● Built with OpenEmbedded/Yocto - one command builds the entire OS ● Fully open, developed as an Open Source project instead of an inhouse product from the start. ● For more information, visit Stefan Schmidt's talk in the Embedded devroom, 17.30 and/or talk to us at the Huawei OSTC stand. 3 What is OpenMandriva? ● A more traditional Linux distribution - controlled by the community, continuing where Mandriva left off after the company behind it went out of business in 2012. Its roots go back to the first Mandrake Linux release in 1998. ● Originally targeting only x86 PCs - Support for additional architectures (aarch64, armv7hnl, RISC-V) added later ● Repositiories contain 17618 packages, built and updated individually, assembled into an installable product with omdv-build-iso or os-image-builder.

Download Android Os for Phone Open Source Mobile OS Alternatives to Android

download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily.
Open Hardware: Pureos and Arduino

Published on Tux Machines (http://www.tuxmachines.org) Home > content > Open Hardware: PureOS and Arduino Open Hardware: PureOS and Arduino By Rianne Schestowitz Created 07/01/2021 - 7:39am Submitted by Rianne Schestowitz on Thursday 7th of January 2021 07:39:57 AM Filed under Hardware [1] PureOS: freedom, privacy, and security [2] A recent blog post from Purism?the company that developed PureOS to run on its security- focused hardware?celebrates three years of FSF endorsement of the Linux distribution. While this endorsement is an achievement that is not as highly valued by our communities as one might think, the work done to obtain and maintain that endorsement is useful even to those who disdain the FSF or disagree with its definition of what makes a distribution "free". While Purism and PureOS have been on our radar for a few years now, it seems worth a look at where things have gone with the distribution?and the company behind it. The blog post notes that PureOS and Purism "sit on a three-legged stool of Freedom, Privacy and Security". The three are intertwined, of course, since PureOS consisting of only free software allows users to ensure there are no antifeatures being slipped into the OS or applications that would impact their privacy or security. Beyond that, free software is an excellent defense against various software supply-chain attacks; in addition the scrutiny of the code afforded to free software, it can also be built in a manner that provides more security... [...] As might be guessed, security and privacy features do not come for free?or even inexpensively.

KDE Plasma 5

Arvo Mägi KDE Plasma 5 Tallinn, 2017 1 Sissejuhatus KDE töökeskkonnale pani aluse saksa programmeerija Matthias Ettrich 14.10.1996. 2016. a oktoobris sai populaarne KDE seega 20. aastaseks. Hea ülevaate KDE ajaloost annab artikkel „19 Years of KDE History: Step by Step.” KDE 4.14 ilmumisega oli KDE saavutanud kasutusküpsuse, kuid edasine areng kippus takerduma – vaja oli põhimõttelisi uuendusi. Otsustati võtta kasutusele iseseisvatel moodulitel põhinev KDE 5 arhitektuur – Qt/Frameworks. Kõik KDE rakendusprogrammid, sh Plasma 5 töölaud, kasutavad ainult konkreetse rakenduse jaoks vajalikke mooduleid. Varem kasutati kõigi rakenduste jaoks ühist suurt teeki, mis raskendas muudatuste tegemist ja pidurdas arendustööd. Qt on C++ programmeerimiskeskkond. Pikaajalise toega Qt 5.9 LTS ilmus 31. mail 2017. KDE Frameworks on 70 moodulist koosnev komplekt, mis lihtsustab Qt keskkonnas KDE programmide koostamist. Frameworks veaparandused ja täiendused ilmuvad iga kuu. KDE Plasma 5 töölaud põhineb KDE Frameworksil (KF5). Töölaua veaparandused ilmuvad iga kuu, vajadusel mitu korda kuus, uued versioonid kord kvartalis. Plasma 5.8 LTS, mis on pikaajalise toega (18 kuud), ilmus 4.10.2016, veidi enne KDE 20. aastaseks saamist. Plasma 5.10 ilmus 30.05.2017. Järgmine pikaajalise toega Plasma 5.12 ilmub 2018. a jaanuaris. Plasma 5 töölaud on pälvinud palju kiitvaid hinnanguid ja sobib igapäevaseks tööks. Eeldab kaasaegset, mitme tuumaga protsessori ja piisava mäluga (vähemalt 4 GB) arvutit. SSD kettalt töötab välkkiirelt. Töölaud on keskkond rakendusprogrammide käivitamiseks ja kasutamiseks. KF5-le on üle viidud kõik KDE põhirakendused (failihaldur Dolphin, pildinäitaja Gwenview, konsool Konsole, teksti- redaktor Kate, ekraanitõmmise võtja Spectacle, videoredaktor Kdenlive, plaadikirjutaja K3b jt). Need on KDE Applications koosseisus, mille uued versioonid ilmuvad kolm korda aastas, veaparandused kord kuus.

Free Software As Commons

FREE SOFTWARE AS COMMONS BETWEEN INFORMATIONAL CAPITALISM AND A NEW MODE OF PRODUCTION By Emrah Irzık Submitted to Central European University Department of Sociology and Social Anthropology In partial fulfillment of the requirements for the degree of Doctor of Philosophy Supervisor: Professor Jakob Rigi CEU eTD Collection Budapest, Hungary 2015 Statement I hereby state that the thesis contains no material accepted for any other degrees in any other institutions. The thesis contains no materials previously written and/or published by another person, except where appropriate acknowledgment is made in the form of bibliographical reference. Emrah Irzık Budapest, November 2015 CEU eTD Collection Abstract Free Software is a particular way of organizing the production and distribution of software that offers a solid alternative to the intellectual property regime by constituting an open commons: non-proprietary, created and held in common by all. Considering that in contemporary capitalism a significant amount of wealth is created through the application of intellectual effort to existing knowledge to produce new, higher compositions of knowledge that can be privately monetized as intellectual property, the challenge that Free Software might present to capitalism is bound to have important transformational potential. This potential needs to be studied both on an empirical level, in its partial and concrete manifestations in actual projects, and investigated more theoretically, to see if Free Software can be characterized as a nascent, new mode of production. This dissertation aims to contribute to the theorization of the relation between Free Software as a commons and the tenets of informational capitalism by means of an analytical study that is supported by an ethnography of a particular instance of Free Software as a project and a community.
